Application filed September 30, Serial No.

To all-whom it may concern:

Be it known that I, CLAEs RYDEN, a citi- Zen of the United States, residing at Provi dence, in the county of Providence and Stateof Rhode Island, have invented certain new and useful Improvements in Winding-Machines, of which the following is aspecifiover the ends.

cation. I

My invention relates-to improvements in winding machines for winding yarn and thread or the likeinto cops orbobbins.

Theobject of my improvement is to pro;

vide a machine for producing cops or bobbins wound with cylindrical layers in such manner as toform them with tapered or conical ends, thereby making them more stable and less liable to-be damaged from the coils becoming displaced or falling down To accomplish this result my improved mechanism provides for automatically "and progressively shortenlng the extent of traverse of the thread-guide,

which disposes the coils. of yarn, throughout:

the complete winding of the cop, thereby gradually reducing the length of the layers of winding as the cop increases in diameter. The invention is fully set forth in the following specification, illustrated by the accompanying drawings, in which Figure 1 is a front elevation of my improved windingmachine, with the driving pulley and clutch-devices shown in section on a vertical plane extending through the axis of the winding-spindle; Fig. 2, an end elevation, part sectional on the line X-X of Fig. 1; Figs. '3, 4, 5 and 6, detail views of the improved transverse-mechanism of the machine; Figs. .7 and 8, detail views of the stopping-mechanism of the machine.

My new machine is similar in general structure to that shown and described in my previous application-for patent, Serial No. 706,063, filed June 26, 1912- It is designed to be built in gangs or series of any suittwo side-members or uprights a, a, joined at the top by an arch or bridge-piece a The side-members a, a are formed with Specification of Letters i?atent.

bearings 00?, a for the horizontally arranged w1nding-spindleB and hubs 0. a for the parallel cross-rod C which issecured therein by suitable means -such, for"'instance,-as the set-screw 0,; Extending outward at each side of the frame A and supported byv a suitable standard Av arranged in back of the. base a is an arm. a terminating in a bearlng a for the rock-shaftD, see also Fig. 2. Unlike the machine of the-application previously referred to, the present one has two rock-shafts, one on,either side of the frame and b'othextending horizontally below and at right-angles to the windingspindle. It will be understood that the rock-shafts extend the whole length ofv the bed or -table -.which supports the several heads or units and-are connected to a cam or other su table device for imparting an oscillating movementto "them. The rockshafts D carry arms D for" transmitting motion 'to the reciprocating thread-guides which are traversed axially of .the winding-v spindles, as more fully explained hereinafter. 1

- In my present machine the winding-spindle B is made'in two separatealining sections band 6', joined in the center by a stepped bearing which is preferably constructed with a reduced portionb of the section b projecting. into an axial bore 6 in the end of the section b. This provides thatthe cop-drivers at either end of the machine Patented Feb. 15.; 1916. t

can be started and stopped independently of I each other so that when the rotation of the cop at one end isarrested, for piecing-up or other cause, it will not necessitate the stopping of the cop at'the other end. Both sections of the spindle B are rotated from a common driving-pulley 'E which is connected thereto by independent clutch-devices F and F'.. The pulley E is driven from a driving belt, not here shown, which is prefer-- ably arranged to connect the'pulleys of all the winding heads toa common "source if s both of the clutch-devices F and F are'thesame, only one need be described. Referring to Fig. 1, the pulley E is formed withbeveled clutch facese', e at its opposite sides. The clutch-member F is-mounted' to slide on a bushing f, mounted'on the spindle-sectionb, and has atapered periphery f adapted to engage the face eof'the pulley E. One end. of the bushing f abuts the end of the hub of secures the collar to the spindle B so that both the collar and bushing rotate therewith.

The key f is also adapted to engage a radialslot f in the rear face of the clutch-member F so that when the latter is connected to the pulley E it drives the spindle-section 6, see

Figs. 1 and 8. The periphery of the collar f isscored with an annular; groove f into which is sprung the end coil of a helical, wire spring f and the opposite end of the spring bears against the clutch-member F to normally hold it in engagement with the pulley E. The clutch-member F is formed with a tapered flange f adapted to be engaged by a lever G, see Fig. 8, to withdraw it from the pulley E to arrest the rotation of the spindle-section b, as more fully explained hereinafter.

the rotation of the opposite spindle-section b. p

The outer end of the spindle B pro3ects a short distance beyond the side of the frame A and is formed with a reduced portion 2) adapted to fit the bore of the cop-tube or quill m on which the cop is wound.

' Usually, wooden quills are employed for this purpose and their ends are slotted at 00, see

Fig. 2, to receive a radially disposed spline or.key b which is carried in the end of the spindle B. The key 6 serves to drive the quill as and the outer end'of the latter is supported on the end of a live spindle h mounted in a sleeve h in the bearing H. The sleeve h is arranged to slide in the bearing H and is operated by a spring to allow its retraction during the insertion of the quill,

but these parts are not here shown in detail as their arrangement is well known in the art. The bearing H surmounts an arm 71. which extendsfrom a hub h secured on a rod H, the latter projecting from the side of the frame A, see Figs. 1 and 2.

Secured in an ear a projecting from the sideof the upright a of the frame A, see

Fig. 2, is a rod 1 which I term the traverse: rod. Its outergend is supported by an arm C reaching up from the rod C to which it is secured by the set-screws 0 Mounted to slide on the traverse-rod I is a sleeve j, see Fig. 3, on which is swiveled the threadguide-holder J carrying the thread-guide k,

the latter formed with a thread-notch k for receiving the thread or yarn and guiding it on to the quill w. The thread-guide I0 is adapted to swing outward, away from the The clutch-member F" is operated in the same manner to control b in.

axis of the winding-spindle, as the yarn is built up on the quill a2, and the upper edge of the guide is maintained in contact with the cop throughout the winding by the Weighted traverse-frame L, see Fig. 2. The traverse-frame L is arranged substantially the same as that described in my previous application, before referred to, with its legs Z pivoted on the rod I and its back Z bearing against the rear face'of the guide-holder J so that the weights 1 act to press the guide against the surface of the cop. The yarn 3 leads down from above through an eye m at the end of an end-stop-lever M, thence over a thread-bail m, and through the notch in in the guide is.

The end-stop-lever M is secured to a rod N. pivoted in bearings Z on the back of the traverse-frame L and is supported in an upright position, as illustrated in Fig. 2, by the tension of the yarn y. The rod N is formed at its inner end with a crank-arm n, the end of which engages an arcuate slot 0 in the curved end of a lever The lever U is pivoted on the side of the frame A and has (a forwardly extending portion 0 formed with an ear 0 to which is secured one end of a helical spring 0 The opposite end of the spring 0 is fastened to a lug a on the frame A and the tendency of the spring is to tilt the forward end of the lever O upward to depress its rear end. Normally, the crank-arm n on the rod N maintains the lever O in the position illustrated in Fig. 2, when the end-stop-lever M is held upright by the tension on the yarn; but when the yarn breaks or is exhausted it will allow the end-stop-lever to tilt backward and this permits the lever O torock under the influence of the spring 0 The tilting of the lever 0 acts to cause the-operation of the stoppingmechanism of the machine to arrest the rotation of the"winding-spindle as now explained.

The forward end of the lever O is provided with a triangular opening 0 in which the end of a wire lever p is adapted to play. The lever p is pivoted at the end of an arm P which is secured to a rod P by a set-screw p. The rod P is supported by an elbowportion p of the arm P which reaches in ward and is secured to the rod H and by, a

second arm 29 also secured to the rod H at its opposite end, seeFig. 1. The rod H extends through both sides of the frame A and is secured fixedly therein by the set-screws The rod P is adapted'to swing about the axis of the rod H and is operated manually by a. handle 1. see Fig. 1, formed by bending the end ofthe rod at right-angles to its main portion. Secured to the inner end of-the rod P by the set-screw g is the clutch-lever G, the movement of the rod acting through this lever to withdraw the clutch-member F from the pulley E, as previously described. Slightly apart from the lever G is a detent-lever S secured on the rod P by a set-screw 8. Referring to Fig. 2, the upper end of the lever S is formed with a shoulder 8" adapted to engage an opposite shoulder s on the end of a. second detent lever S. The lever Sis pivoted on a bearing 8 extending from a lug a at the top of the frame A, see Fig. 1, and arranged in a pocket a surrounding the bearing is a coiled springs adapted to swing the lever in the direction indicated by the arrow 2, Fig.2. The tendency of the spring 8 is normally to maintain the, detent-shoulders s ands locked together during the operation of the machine; but when the rod P is moved bodily in the direction indicated by the arrow 3, Fig. 2, the detent-shoulders will be released and the face 8 of the lever S bearing against the face s of the lever S will cause the latter to move the rod P still farther in the same direction. This action serves to carry the tapered end of the clutchlever G into engagement with the corresponding tapered flange f of the clutchmember F to withdraw the latter from the pulley E. It is called to attention that during this operation the end of the lever S does not ride clear off from the end of the lever S, but, on the contrary, the two levers remain in such relation that their shoulders may be readily engaged again through manual operation of the handle P I Referring to Fig. 1, it will be observed that the wire lever p straddles the arm P,

and is formed with an upper arm 72*, see Fig. 2, which reaches in below the windingspindle B. Secured to the spindle site the arm p is a knock-off wheel I) formed with ratchet-teeth or spurs b on its periphery. ,The spindle B rotates in the direction indicated by the arrow 4, see Fig. 2, and when the lever p is thrown up into the position here illustrated the end of the arm p will be engaged byone of the'spurs b to force the arm P outward and swing the rod P to actuate the clutch-operating lever G. The lever p also has a guard-arm p which comes into contact with the under side of the wheel b to prevent the arm 72* from being thrown up above the wheel. The

lever is operated to-engage its arm 70* with the knock-off .wheel I) the tilting movement of. the lever O which engages its end through the slot or opening 0 It is also adapted to be operated bymeans connected with the traverse-controlling mechanism hereinafter explained and for thisreason the stopping devices have been described in detail. I

Mounted on the cross-rod C, outside of theframe' A and secured by the set-screws 75 t are two inverted T-shaped meinbers T, T which support a pair of vertically extending rods t, t.. Mounted to slide up I Figs. 2 and 3.

the under side B oppoand down on the rods 25, t is a frame U, preferably formed of sheet-metal with legs, u, it having earsv u, u bent over at='rightangles andjbored to receive the rods, see At the upper corners of the' frame U are two ears a 711 curled over to surround the rods t,- t and serving to maintain the frame ,in a vertical position. At the top of the frame U are two uprights if, a formed with double ears u, u bored to receive a' horizontal rod' a which is held in position by the set-screws u", u Mounted rotatably on the rod a betweenthe uprights if, u is'a pressure roll U arranged directlyv under the cop quill w and adapted to bear on itsperiphery so that as the layers of yarn are built up on the quill the growth in diameter of the cop will fprce the frame downward on the rods t,-t.

Extending from the outer side of the frame U is an arm u to which is pivoted at u a dogging-lever u". The inner-edge of the dog u is formed with an eccentric cam- .face u adapted to impinge on ,the side ofthe rod 25. The dog a isreleased by a finger-piece u, and a stop u bent out from its lower edge isadapted to engage ofthe arm u to limit the upward movement of its dogging end: Normally, the weight of the inner end of the dog tends to frictionally engage it with the rod t so that the frame U is restrained from upward movement ,while being free to slide downward on the rods t, t.- This prevents the roll U from, vibrating or, jumping up and down under the efi'ectof irrlegularities on the periphery of the cop.

ounted on the opposite side of the frame U is a stop-finger V, preferably formed of sheet-metal and secured in position by a screw '0 reaching through a vertical slot '0', see Figs. 2 and 3. An ear '0 on the finger engages a second slot 0 in the frame toprevent it .fromturning on the screw a.

The finger V reaches'outat right-angles to the frame U, as shown most clearly in Fig. 2, and is adapted to engage the downwardly-extending arm?) of a lever V, see also Fig. 3. The lever V is pivoted at '0 on alug-p extending rearwardly from the arm P, see Fig. 7, and has an upwardly extending arm '0 bent at right-angles ate) and adapted to engage the end of the lever 72, as shown in Figs. 2 and 3. Referring to Fig. 3, the edge of the arm a of the lever V" isformed with a curved Cam-face '0 and as the frameU slides down on the rods t, -t the finger V rides over'this face and tilts the lever V to elevate its right-angled portion 1)". This action raises the lever 79 to-carry its, end into engagement with the knock-off wheel 6 andthereby cause the operation of the clutch-releasing devices as previously explained. The stop-finger V can be adjusted upand down on the frame U by sliding its screw 4) in the slot 4) and this determines the size of the I cop being wound. That is to say, the finger V is set according to the size of cop desired and when the winding reaches the predetermined diameter the frame U will have been forced down far enough to cause the finger to trip the lever V and stop the machine.

The improved traverse mechanism of the machine consists of the following-described instrumentalities: Referring to Figs. 1 and 2, the rocker-arm D. which imparts reciprocation to the threadguide la is secured to one end of a crescent-shaped block (I, by means of screws (Z, (l, the block d being adapted to fit the top of the rockershaftD and fastened thereto by a bolt d At the opposite end of the block d is fastened a second arm D held by the screws d (P, which reaches up adjacent the traverse-rod I. The thread-guide holder J is pivoted on the sleeve j by means of its two legs j, j held in place by wire rings 7' j sprung into peripheral grooves on the sleeve, see Fig. 3. The legs 9'', j straddle a member J, also pivoted on the-sleeve j, and having a. depending arm 7' formed with a slot j see Fig. 4. The member J is preferably constructed of sheet-metal, bentat its top to surround the sleeve y and extending downward in two parallel sides 7" ,.j which form the arm j see Fig. 2. The "sleeve and its depending ,;arm j constitute the traverse slide for reciprocating the threadguide it. The sides 9' 3' of the arm j straddle the arm D which is also formed with a slot d Referring to Fig. 5, which is an enlarged sectional View of the arms D and 7' taken on the line ZZ of Fig; 3, the slot 7' in the arm j is part-spherical in cross-section to adapt it to inclose a ball to which also fits the slot 0Z in the arm D The ball w slides on a rod W which is formed with an enlarged portion w pivoted on a pin wt extending through two ears (Z (1 at the top of the arm-D, see Fig. 2. This arrangement provides for connecting the arm D and member J to move together to impart reciprocation to the latter, while the ball-- and-socket joint allows the rod W to rock on its pivot'to slide the ball to up and down in the slots in the arms j and D Adapted to slide on the rod W between the ball to and pivot w is a roll w formed with an annular, concave groove w seeFig. 6. The lower edge M13 of the frame U is formed as an arc, substantially concentric with the axis of the rocker-shaft D when the frame U is in its uppermost position, and this edge engages the groove to of the roll w At the rear of the pivot to the rod W is provided with a series of holes 10 into which the end of a coil of spring 2 may be hooked.

innea The opposite end of the spring is secured to an ear d bent out from the arm D adjacent its lower end. The spring 2 tends to maintain the rod W in a substantially horizontal position with the ball w at the upper end of the slot 03 in the arm D It also acts to resist the downward movement of the frame U on the rods t, t and serves to maintain the, roll U bearing against the surface of the cop. The amount of pressure of the roll on the cop can be regulated by adjusting the end of the spring in the holes 105 to vary the leverage of the rod W. At the commencement of the winding the pressureroll U is in its uppermost position, bearing against the cop-quill m, as illustrated in Fig. 3, and the ball to is at the upper end of the slot (Z in the arm D so that the maximum extent of traverse is imparted to the threadguide is. As the winding continues the growth of thecop forces the roll U downward, away from the axis of the windingspindle, and the frame U, bearing on the roll 10 tilts the rod W downwardly as shown in Fig. 2. This carries the ball to downward in the grooves d of the arm D so that'the operative length of the arm is shortened, and hence the extent of traverse of the thread guide is reduced.

The operation of the complete machine is as follows: Assuming that the machine is at rest, the quill 00 is placed in position by mounting its ends on the live-spindle h and spindle-section b with the spline b engaging the slot 00. The yarn g is drawn down from the source of supply, generally placed above the machine, but not here shown, led

through the eye m on the end-stop-lever M,

and thence over the thread-bail m to the quill m, to which the end is secured. The dogging-lever 11, on the frame U is now released to allow the pressure-roll U to be carried up by the action of the spring 2 to bear against the quill'm. As in'the machine of my previous application, before referred to, the thread-guide is reciprocates constantly; that is to say, it is not stopped during the arrest of rotation of the windingspindle. When the spindle is stopped, however, the thread-bail m is raised automatically and the yarn is lifted out of the notch k in the thread-guide is so that it is not re-* ciprocated in relation to the quill. After the traverse-frame L has been adjusted to bring and allowsthe latter to be moved into en- 'gagement with the pulley E to rotate the spindle-section b and, thereby, the cop-quill m. The detent-shoulders s ,and s on the levers S and S are, in the meantime, carried into engagement to maintain the lever G away from the clutch-member F and these parts are held in the position illustrated in Fig. 2 during the winding of the cop. As

the winding-spindle starts to rotate the.

the cop.

As the layers of yarn build up on the quill iv the pressure-roll U is forced downward to slide the frame U. down on the rods 25 and 6. As, the arms D and D are oscillated back and forth by the rocker-shaft D the roll w slides along the lower, arcuate edge u of the frame U. Now, as the frame moves downward its pressure on the roll to will tilt one end ofthe rod W downward, against the action of the spring z on its opposite end, and the ball to will slide gradually downward in the slot 61* of the arm D This action alters the point of connection of the arm D with the arm j of the traverse-slide; that is to say, the operative length of the arm D is gradually shortened so that the extent of traverse imparted to the thread-guide becomes less and less.

Referring to Fig. 1, the dot-and-dash lines Y represent the outline of the cop and it will be seen that, whereas the first layer extends substantially the whole length of the quill a", subsequent layers become shorter and shorter as the winding proceeds, so that the ends of the cop assume a conical form. I have shown the machine arranged to produce a cop with its outer layer approximately two-thirds the length of its inner one and this provides a substantialtaper at the ends of the cop. These proportions can be' varied somewhat, however, by the adjust ment of certain elements of the mechanism ried farther away from the pivot-point of the rod, and hence the movement of the pressure-roll outward from the axis of the cop will impart less movement to the ball 10. This will result in a lesser change in the operative length of the arm D and, therefore, the shortening of the traverse of the thread-guide is more gradual so that the cop will be wound with its ends havingless taper. With the ordinary materials a slight taper at the ends of the cop is sufficient to prevent the coils from slipping and becoming misplaced; but for winding linen, silk or other hard-twisted, slippery threads the -.max1mum taper is advisable.

Heretofore, it has beenfoundalmost impossible to wind hard, firm cops of these materials by building up the layers with squareends. The constrictive force of the outer layers of winding will invariably displace the end coils and cause the ends'of the cop to become bulged or malformed so that the thread cannot be unwound freely, and even if the winding operation, itself, is successful, such forms of cops do not retain their shape, and therefore do not deliver freely from the shuttle. The end coils are much more liable to slip off from a square-ended cop and in such eventthey become caught on the quill or snarled and tangled so that much of the material is often wasted in unwinding it.

My new machine produces a cop which is much more stable and free from the disadvantages noted and provides a marked improvement in the art. i

The mechanism of the machine is simple and directsacting, positive in its control of the traverse of the thread-guide and exceptionally easyto operate.

Various modifications might be made in I the form and arrangement of the parts of. my new device without. departing: from the spirit or scope of the invention.

Therefore, without limiting myself to the,

exact construction shown and described, what I claim is a 1. In a winding machine, the combinationl with the winding-spindle, of a thread guide adapted to be traversed with a straight li'ne movement maintained constantly parallel rate oscillating arm to reciprocate the guide,
